I got mine yesterday (see "Icingdeath" joke in stupid names thread on 4E forum). It looks better than the pictures I saw online. The wings are especially nicely done, but the dragon's posture (hunched over with T-Rex arms) makes it look kind of feeble or something.
The Drizzt and Wulfgar figs are okay; I'm not a Drizzt fan so I didn't care about them much anyway. Nowhere near as cool as my new Kuo-Toa Whip fig from Night Below
Overall, I would rate the dragons thusly from worst to best: red, white, blue, black. The black has the most dynamic and dramatic pose -- to me, it just screams "malevolent spellslinging bad@$$." Which is good, very good.
The Gargantuan White is still a cool fig though, and I like white dragons in general (hell, I used to go to a martial arts school called White Dragon), and I don't regret the purchase at all. I hope to kill PCs with this fig. Viking PCs, perhaps, in the dead of winter...
